Reactions of [RuCl_2(NO)(terpy)]~+ (terpy = 2,2' : 6',2''-terpyridine) with mono anions such as NO_2~-, Br~- and N_3~-, and structural studies on terpyridineruthenium having a nitrosyl ligand

摘要

[RuCl_2(NO)(terpy)]PF_6 ([1]PF_6) has been synthesizd by the reaction of K_2[RuCl_5(NO)] with terpy and characterized by single-crystal X-ray crystallography. [1]PF_6 has a stucture in which the two chloro ligands are located trans to each other with th nitrosyl ligand on the plane of the terpy ligand. Reactions of [1]PF_6 with mono anions such as NO_2~-, Br~- and N_3~- have been investigated. Its reactions with NO_2~- in H_2O and CH_3OH afford nitrosylterpyridineruthenium complexes, [Ru(OH)(NO_2)(NO)(terpy)]PF_6 ([2]PF_) and [RuCl(OCH_3)(NO)(terpy)]PF_6 ([3]PF_6), respectively, whose geometrical configurations differ from that of [1]~+. The Br~--substituted complex of [1]~+, [RuBr_2(NO)(terpy)]PF_6 ([4]PF_6), and two solvated complexes, [RuCl_2(CH_3CN)(terpy)] ([5]) and [RuCl(CH_3CN)_2(terpy)]PF_6 ([6]PF_6), have been formed in its reactions with Br~- and N_3~-. Structures of [2]PF_6, [3]PF_6 and [4]PF_6 have been determined by singal-crystal X-ray crystallography and compared with each other.
